Abstract

A method for converting a ligated-metal into chemical components of the ligated-metal includes forming an ionized zone that can convert the ligated-metal to a reduced ligated-metal intermediate. The ligated-metal is directed into the ionized zone, whereby the ligated-metal is converted to a reduced ligated-metal intermediate, thereby causing a thermodynamically stable metal-ligand bond of the ligated-metal to be electronically destabilized and inducing subsequent metal-ligand bond rupture. The reduced ligated-metal intermediate is converted by the metal-ligand bond rupture into chemical components of the ligated-metal. Ligated-metals that are suitable for processing by the method of the invention include, for example: uranium hexafluoride (UF.sub.6); sodium chloride (NaCl); and metal halides, such as iron trichloride (FeCl.sub.3). Chemical components that can be recovered from the ligated-metal include, for example, metals and gases derived from the ligand component of the ligated-metals.
